3 SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using this product, please read this manual and the relevant manuals carefully and pay full attention to safety to handle the product correctly. The precautions given in this manual are concerned with this product only. For the safety precautions of the programmable controller system, refer to the user s manual for the CPU module used. In this manual, the safety precautions are classified into two levels: " WARNING" and " CAUTION". Under some circumstances, failure to observe the precautions given under " CAUTION" may lead to serious consequences. Observe the precautions of both levels because they are important for personal and system safety. Make sure that the end users read this manual and then keep the manual in a safe place for future reference. [Design Precautions] WARNING Do not write any data to the system area of the buffer memory in the intelligent function module. Also, do not use any use prohibited signals as an output signal from the programmable controller CPU to the intelligent function module. Doing so may cause malfunction of the programmable controller system. CAUTION Do not install the control lines or communication cables together with the main circuit lines or power cables. Keep a distance of 100mm or more between them. Failure to do so may result in malfunction due to noise. A - 1 A - 1

4 [Installation Precautions] CAUTION Use the programmable controller in an environment that meets the general specifications in the user s manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product. To mount the module, while pressing the module mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the module. When using the programmable controller in an environment of frequent vibrations, fix the module with a screw. Tighten the screws within the specified torque range. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction. Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may result in damage to the product. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used. Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant chapter in this manual. Do not directly touch any conductive and electronic component of the module. Doing so can cause malfunction or failure of the module. [Wiring Precautions] WARNING After wiring, attach the included terminal cover to the module before turning it on for operation. Failure to do so may result in electric shock. CAUTION Individually ground the FG terminal of the programmable controller with a ground resistance of 100 or less. Failure to do so may result in electric shock or malfunction. Tighten the terminal screws within the specified torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction. Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction. A protective film is attached to the top of the module to prevent foreign matter, such as wire chips, from entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation. Use applicable solderless terminals and tighten them with the specified torque. If any solderless spade terminal is used, it may be disconnected when the terminal screw comes loose, resulting in failure. Keep a distance of 100mm or more between a thermocouple and the main circuit line or AC control lines. Also, keep the thermocouple away from a circuit that includes harmonics, such as a highvoltage circuit and a load circuit of an inverter. If not, the thermocouple is more likely to be affected by noise, surges, and induction. A - 2 A - 2

5 [Startup and Maintenance Precautions] WARNING Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the terminal screws, connector screws, or module fixing screws. Failure to do so may result in electric shock or cause the module to fail or malfunction. Undertightening can cause drop of the screw, short circuit or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction. CAUTION Do not disassemble or modify the modules. Doing so may cause failure, malfunction, injury, or a fire. Shut off the external power supply (all phases) used in the system before mounting or removing the module. Failure to do so may cause the module to fail or malfunction. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used. Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant chapter in this manual. After the first use of the product, do not mount/remove the module to/from the base unit, and the terminal block to/from the module more than 50 times (IEC compliant). Exceeding the limit of 50 times may cause malfunction. Before handling the module, touch a conducting object such as a grounded metal to discharge the static electricity from the human body. Failure to do so may cause the module to fail or malfunction. [Disposal Precaution] CAUTION When disposing of this product, treat it as industrial waste. A - 3 A - 3

16 MEMO A - 14 A - 14

17 1 OVERVIEW 1 OVERVIEW This user's manual provides the specifications, handling instructions, programming procedures and others of the Q64TD thermocouple input module (abbreviated to the Q64TD) and Q64TDV-GH channel isolated thermocouple/micro voltage input module (abbreviated to the Q64TDV-GH) used with the series CPU module (hereafter abbreviated to the CPU). The Q64TD is a module designed to convert thermocouple input values from outside the programmable controller into 16-bit signed binary measured temperature values and 16-bit signed binary scaling values (ratios). 1 1: Refer to Section for details of the scaling values. In addition to the temperature measurement functions of the Q64TD, the Q64TDV-GH has a function that converts a micro voltage signal into a 16-bit, signed binary data. 1: Refer to Section for details of the scaling value

18 1 OVERVIEW 1.1 Features 1 (1) Channels isolated Both the Q64TD and Q64TDV-GH are channel isolated modules. (2) 4 channels of temperatures measured by one module One Q64TD module can measure temperatures of four channels. It can also convert the detected temperature values into scaling values (ratios (%)). (3) Micro voltages of four channels can be converted on one module (Q64TDV-GH only) One Q64TDV-GH module can make micro voltage conversion of four channels. It can also convert the detected micro voltage conversion values into scaling values (ratio values (%)). (4) Setting of conversion enable/disable You can make a conversion enable/disable setting for each channel. Disabling unused channels for conversion reduces sampling time. It also prevents unnecessary disconnection detection on unused channels. (5) Thermocouples conforming to JIS Standards usable You can use eight different thermocouples (K, E, J, T, B, R, S, N) conforming to the JIS Standards. You can also select the thermocouple type for each channel using GX Developer. (6) Disconnection detection The disconnection of a thermocouple or compensation conductor can be detected on each channel. (7) Selection of sampling processing/time averaging processing/count averaging processing As a conversion processing method, you can choose sampling processing, time averaging processing or count averaging processing on each channel. (8) Pt100 temperature-measuring resistor for cold junction temperature compensation The Pt100 temperature-measuring resistor connected makes cold junction temperature compensation automatically. (9) Setting of Pt100 cold junction temperature compensation enable/disable Disabling cold junction temperature compensation with Pt100 temperaturemeasuring resistor enables cold junction temperature compensation to be made outside the module. By providing a precision ice bath externally, the thermoelectromotive force generated at the tip of the thermocouple can be led to the Q64TD/Q64TDV-GH without any change, improving the cold junction temperature compensation accuracy. (10) Error compensation by offset/gain value setting Error compensation can be made by setting offset and gain values on each channel. As the offset and gain values, you can make selection from user range setting and factory default setting

19 1 OVERVIEW 1.2 Added Functions (11) Warning output If the temperature detected is outside the preset measurement range, a warning can be output for each channel. (12) Online module change A module can be replaced without stopping the system. Furthermore, original specifications can be transferred to the replacement module by using a sequence program and by executing the following. (Note that this is for modules of the same model only.) Inheritance of offset/gain settings to the new Q64TD/Q64TDV-GH after online module change Transfer of offset/gain settings to the other Q64TD/Q64TDV-GH mounted on the other slot (13) Easy setting with GX Confogurator-TI The use of GX Configurator-TI, which is sold separately, reduces sequence programming since Q64TD/Q64TDV-GH settings can be configured on the screen. In addition, setting status and operating status of modules can be checked easily. The following is a function added for the Q64TD/Q64TDV-GH. Item Applicable module Function overview Online module change Mode switching that does not require CPU to be reset Conversion setting for disconnection detection Function version C or later Function version C or later First 5 digits of product information are or later You can change the module without stopping the system. The CPU of function version C or later is required. Using the mode switching setting (buffer memory addresses 158, 159: Un\G158, Un\G159) and operating condition setting request (Y9), the module is switched between the normal mode and offset/gain setting mode without the CPU being reset. Using the dedicated instruction (G(P).OFFGAN), the module is switched between the normal mode and offset/gain setting mode without the CPU being reset. Using GX Configurator-TI, the module is switched between the normal mode and offset/gain setting mode without the CPU being reset. For values to be stored in the CH measured temperature value/micro voltage conversion value (buffer memory addresses 11 to 14: Un\G11 to 14) in the case of disconnection detection, any of "Value immediately before disconnection", "Up scale (maximum value of measured temperature range + 5% of measured temperature range)", "Down scale (minimum value of measured temperature range 5% of measured temperature range)" or "Given value" can be selected.

27 2 SYSTEM CONFIGURATION 2.4 Precautions for System Configuration The Q64TD/Q64TDV-GH measures a temperature on the basis of the temperature of a terminal block. Therefore, depending on a system configuration (especially for the case when two or more the Q64TD/Q64TDV-GH are mounted side by side, or when the Q64TD/Q64TDV-GH is mounted next to the power supply module or the CPU module), the temperature distribution of the terminal block becomes inhomogeneous because of the effect of heat emitted from each module, thus the measured temperature error may become large. In such case, use a terminal block converter module and a dedicated cable shown below to prevent the error caused by the heat emission. The following table lists the dedicated cable and the terminal block converter module.

37 3 SPECIFICATIONS 3.2 Function List The following table lists the Q64TD/Q64TDV-GH functions. Item Description Refer To Temperature conversion function Micro voltage conversion function (Q64TDV-GH only) Temperature conversion system (Q64TD) Temperature/micro voltage conversion system (Q64TDV-GH) Conversion enable/disable function Input type selection function Disconnection detection function Conversion setting for disconnection detection function Pt100 cold junction temperature compensation yes/no setting function Warning output function Scaling function Offset/gain setting function This function allows temperature data to be imported by connecting a thermocouple. Temperature data are 16-bit signed binary (-2700 to 18200) and stored into buffer memory. This function converts a -100mV to +100mV micro voltage into a 16-bit, signed binary ( to 25000) and stores it into the buffer memory. (1) Sampling processing A temperature input value is converted into a temperature one by one on each channel and a measured temperature value is output after every conversion. (2) Averaging processing Temperature conversion is averaged by count or time on each channel and an averaged value is stored. (1) Sampling processing A temperature/micro voltage input value is converted one by one on each channel and a measured temperature value is output after every conversion. (2) Averaging processing Temperature conversion is averaged by count or time on each channel and an averaged value/micro voltage conversion value is stored. This function specifies whether temperature/micro voltage conversion is enabled or disabled on each channel. Setting temperature/micro voltage conversion enable/disable reduces the processing time of unused channels. In addition, it prevents unnecessary disconnection detection of unused channels. Section Section Section Section Section This function sets the input type per channel. Section 4.5 This function detects the disconnection of the connected thermocouple/micro voltage signal cable on each channel. For values to be stored in the CH measured temperature value/micro voltage value (buffer memory addresses 11 to 14: Un\G11 to 14) in the case of disconnection detection, any of "Value immediately before disconnection", "Up scale (maximum value of measured temperature range + 5% of measured temperature range)", "Down scale (minimum value of measured temperature range 5% of measured temperature range)" or "Given value" can be selected. This function determines whether cold junction temperature compensation is made or not using the Pt100 attached to the terminals. Use this function to measure temperatures with higher accuracy than the cold junction temperature compensation accuracy ( 1 ) of the Pt100 that is attached to the Q64TD/Q64TDV-GH. The cold junction temperature compensation accuracy can be improved by disabling the cold junction temperature compensation of the Pt100 and providing a precision ice bath externally. This function outputs a warning when the measured temperature value/micro voltage conversion value is equal to or more than the warning output upper limit value or is equal to or less than the warning output lower limit value. This function can convert a measured temperature value/micro voltage conversion value into a preset range ratio (%) and import it into buffer memory. This function compensates for an error of a measured temperature value or changes the conversion characteristic of a micro voltage conversion value.

38 3 SPECIFICATIONS Micro voltage input/output conversion characteristic (Q64TDV-GH only) A micro voltage input/output conversion characteristic indicates the slope of a straight line that connects an offset value and gain value when an external micro voltage signal is converted into a digital value. Offset value A micro voltage input value whose digital output value will be Gain value A micro voltage input value whose digital output value will be The following indicates the micro voltage input/output conversion characteristic as set at the factory (offset value: -100mV, gain value: 100mV) Digital output value mV 0mV 100mV Micro voltage input value POINT (1) Use the module within the micro voltage input range and digital output range. Outside those ranges, the maximum resolution and accuracy may not fall within the ranges of the performance specifications. (Avoid using the dotted line areas in the chart.) (2) Do not input voltage of 5V or higher, or -5V or lower. Doing so may damage the elements

39 3 SPECIFICATIONS Temperature conversion system (Q64TD) There are two temperature conversion systems, sampling processing and averaging processing. (1) Sampling processing A temperature input value is converted into a measured temperature value successively and the digital output value is stored into the buffer memory. Sampling processing time varies with the number of used channels (number of channels set to enable temperature conversion). (Processing time) = (number of used channels) (40ms) [Example] Sampling time is 120ms when three channels, channels 1, 2 and 4, are enabled for conversion. 3 channels 40ms = 120ms (2) Averaging processing The temperatures of the channels specified for averaging processing are converted by the preset count or for the preset period of time, the sum of the resultant values except the maximum and minimum values is averaged, and the result is stored into the buffer memory. Averaging processing requires at least 2 times of conversion processing excluding the maximum and the minimum values. (a) Time averaging processing The processing count within the preset time varies with the number of used channels (number of channels set to enable temperature conversion). (Processing count) = (preset time) (number of used channels) (40ms) Setting range of preset time is 160 to 5000ms. When setting a value out of the setting range, an error (error code 20 ) occurs. [Example] The sampling count is 4.75 when four channels, channels 1, 2, 3 and 4, are enabled for conversion and the preset time is 760ms. 760ms (4 channels 40ms) = 4.75 Since the fractional portion of an indivisible value is dropped, the sampling count is 4 times. (b) Count averaging processing The time taken to store a count-averaged value into buffer memory varies with the number of used channels (number of channels set to enable temperature conversion). (Processing time) = (preset count) (number of used channels) (40ms) Setting range of preset count is 4 to times. When setting a value out of the setting range, an error (error code 30 ) occurs. [Example] An average value is output ever 320ms when two channels, channels 3 and 4, are enabled for conversion and the preset count is 4. 4 times (2 channels 40ms) = 320ms

40 3 SPECIFICATIONS Temperature/micro voltage conversion system (Q64TDV-GH) Temperature/micro voltage conversion can either be made by sampling processing or averaging processing. (1) Sampling processing A temperature/micro voltage input value is converted successively and a digital output value is stored into the buffer memory. The conversion speed changes depending on the number of channels used (number of channels set for conversion enable). (Conversion speed) = (sampling period) 3 = {(number of used channels) (20ms)} 3 [Example] When 2 channels are enabled for conversion (Conversion speed) = (sampling period) 3 = (20ms 2 channels) 3 = 120ms Input 1) Input 2) Conversion processing CH1 CH2 CH1 CH2 CH1 CH2 CH1 CH2 CH1 CH2 Buffer memory Conversion speed Conversion speed Input 1) Input 2) (2) Averaging processing The input value of the channel specified for averaging processing is converted by the preset number of times or for the preset period of time, the sum of the resultant values except the maximum and minimum values is averaged, and the average value is stored into the buffer memory. Averaging processing requires at least 2 times of conversion processing excluding the maximum and the minimum values. (a) Time averaging processing The number of processings performed within the preset time changes depending on the number of channels used (number of channels set for conversion enable). (preset time) (Processing count) = (number of used channels) (20ms) Setting range of preset time is 80 to 2500ms. When setting a value out of the setting range, an error (error code 20 ) occurs. [Example] When four channels, channels 1, 2, 3 and 4, are enabled for conversion and the preset time is 760ms, the sampling count is ms (4 channels (20ms) = 9.5 If the result cannot be divided, its fractional portion is rounded down and the sampling count is 9 times

41 3 SPECIFICATIONS (b) Count averaging processing The time when the count-based average value is stored into the buffer memory changes depending on the number of channels used (number of channels set for conversion enable). (Processing time) = (preset count) (number of used channels) (20ms) Setting range of preset count is 4 to 62500ms. When setting a value out of the setting range, an error (error code 30 ) occurs. [Example] When two channels, channels 3 and 4, are enabled for conversion and the preset count is 4, the average value is output per 160ms. 4 times (2 channels 20ms) = 160ms

42 3 SPECIFICATIONS Conversion setting for disconnection detection function (1) For values to be stored in the CH measured temperature value/micro voltage value (buffer memory addresses 11 to 14: Un\G11 to 14) in the case of disconnection detection, any of "Value immediately before disconnection", "Up scale (maximum value of measured temperature range + 5% of measured temperature range)", "Down scale (minimum value of measured temperature range 5% of measured temperature range)" or "Given value" can be selected. Setting is available for each channel. (2) This function can be utilized only for channels where temperature conversion is enabled. (3) When Up scale (1H) or Down scale (2H) is set, an Up scale value (maximum value of measured temperature range + 5% of measured temperature range) or a Down scale value (minimum value of measured temperature range 5% of measured temperature range) of the individual range is stored respectively. Input type Set value Measurement range Up scale Down scale Thermocouple K to Thermocouple E to Thermocouple J to Thermocouple T to Thermocouple B 4 0 to Thermocouple R 5-50 to Thermocouple S 6-50 to Thermocouple N to Micro voltage input to For the Up scale and Down scale of the micro voltage input, the maximum and minimum of the micro voltage conversion values are applied. (4) When Given value(3h) is selected, set a value for the CH conversion setting for disconnection detection (buffer memory addresses 150 to 153: Un\G150 to 153) in units of 0.1. The value set in the area is stored in CH measured temperature value/micro voltage value when disconnection is detected

(2) Refer to Chapter 7 for the user range restoration. Module ready (X0) ON Offset/gain setting mode status flag (XA) XC XD Disconnection Detection Flag Warning Output Signal User range write request (YA) (1) The input circuit for the thermocouple of the conversion-enabled channel turns ON the Disconnection Detection Flag (XC) when any input signal line including the thermocouple/micro voltage signal line is disconnected. For the channel where disconnection is detected, a value based on the Conversion setting for disconnection detection (buffer memory address 148: Un\G148) is stored in the CH measured temperature value/micro voltage conversion value (buffer memory addresses 11 to 14: Un\G11 to 14). Conversion of the channels not disconnected is continued. (2) For temperature conversion values to be stored when the Disconnection Detection Flag (XC) turns ON, any of "Value immediately before disconnection", "Up scale (maximum value of measured temperature range + 5% of measured temperature range)", "Down scale (minimum value of measured temperature range 5% of measured temperature range)" or "Given value" can be selected. (Refer to Section ) (3) Removing the cause of disconnection and turning ON the Error Clear Request (YF) turns OFF the Disconnection Detection Flag (XC). (4) When the line connection is recovered, the temperature conversion value update is restarted independently of the Disconnection Detection Flag (XC) reset. (1) This signal turns on when the measured temperature value/micro voltage conversion value has fallen out of the temperature range set in the warning output upper/lower limit values (buffer memory addresses 86 to 101: Un\G86 to 101) on any of the channels enabled for conversion. (2) This signal turns off automatically as soon as the measured temperature value/micro voltage conversion value returned to within the ranges on all channels enabled for conversion

The setting for the measured temperature value is in 0.1 increments. (2) The warning output range can be set in four levels of the warning output upper upper value, upper lower value, lower upper value and lower lower value. (3) When the detected measured temperature value is higher than or equal to the warning output upper upper limit value, or lower than or equal to the warning output lower lower limit value (when the value enters the warning output range), a warning occurs. When a warning occurs, "1" is stored to the bit of the corresponding channel in the warning output flag (buffer memory address 48: Un\G48), and the warning output signal (XD) turns ON. (4) After a warning occurrence, when the temperature value is lower than the warning output upper lower limit value or higher than the warning output lower upper limit value (when the value returns to within the setting range), the warning is cleared. When the warning is cleared, "0" is stored to the bit of the corresponding channel in the warning output flag (buffer memory address 48: Un\G48).

77 4 SETUP AND PROCEDURES BEFORE OPERATION 4.4 Wiring Wiring instructions The wiring precautions and examples of module connection are provided below. In order to optimize the functions of the Q64TD/Q64TDV-GH and ensure system reliability, external wiring that is protected from noise is required. Please observe the following precautions for external wiring: External wiring (1) Use separate cables for the AC control circuit and Q64TD/Q64TDV-GH's external input signals to avoid the influence of AC side surges and inductions. (2) Always place the thermocouple/micro voltage signal cable at least 100mm away from the main circuit cables and AC control lines. Fully keep it away from high-voltage cables and circuits which include harmonics, such as an inverter's load circuit. Not doing so will make the module more susceptible to noises, surges and inductions. (3) Insulation-sleeved crimping terminals cannot be used with the terminal block. It is recommended to fit mark tubes or insulation tubes to the wire connection parts of the crimping terminals. (1) Thermocouple 1 As cables, always use shielded compensation conductors. Also, wire the shielded cables as short as possible. 2 Always connect to the earth terminal of the control box

83 4 SETUP AND PROCEDURES BEFORE OPERATION 1 The mode switching (normal mode to offset/gain setting mode to normal mode) method is given below. Dedicated instruction (G.OFFGAN)... Refer to Section 4.6 (3), (a) Setting made to mode switching setting (buffer memory addresses 158, 159: Un\G158, Un\G159) and turning the operation condition setting request (Y9) from OFF to ON... Refer to Section 4.6 (3), (b) Intelligent function module switch setting... Refer to Section 4.5, Section 4.6 (3), (c) (After intelligent function module switch setting, reset the programmable controller CPU or switch power OFF, then ON.) 2 Do not perform the following during the steps marked 2 If any of the following is performed, the data in E 2 PROM will have a problem and the Q64TD/Q64TDV-GH may not operate normally. Powering off the programmable controller CPU Resetting the programmable controller CPU POINT Check the offset and gain values in the actual operating status. By turning on the User Range Write Request (YA), the offset and gain values are stored into the E 2 PROM and will not be erased at power-off. Make offset/gain setting within the measured temperature guarantee range (refer to Section (2), Section (2)) or within the measurable voltage range (refer to Section (3)). If setting is made outside the measured temperature guarantee range or measurable voltage range, the resolution and accuracy may not fall within the ranges of the performance specifications. Set the offset and gain values within the ranges where the following conditions are satisfied. (Gain value) - (offset value) > 0.1 [ ] (for temperature input) or (Gain value) - (offset value) > 4 [ V] (for micro voltage input) Offset/gain setting may be made for two or more channels at the same time. Do not set the offset and gain values concurrently. Doing so will cause an error, lighting up the ERROR LED. If an error occurs during offset/gain setting, setting can be continued on another channel or the like. However, since the error remains occurring, turn on the Error Clear Request (YF) when you want to clear the error. At the time of offset/gain setting, turn ON the user range write request (YA) to write the values to the E 2 PROM. Data can be written to the E 2 PROM up to 100 thousand times. To prevent accidental write to the E 2 PROM, an error will occur and the error code (buffer memory address 19: Un\G19) will be stored if write is performed 26 consecutive times. (Refer to Section ) 1 If an error (error code: 40 ) occurs during offset/gain setting, re-set the correct offset/gain value. The offset/gain value of the channel where the error has occurred is not written to the Q64TD/Q64TDV-GH. ( 1 indicates the corresponding channel number.) The module ready (X0) turns from OFF to ON when the offset/gain setting mode is switched to the normal mode by the setting of the dedicated instruction (G(P).OFFGAN) or mode switching setting (buffer memory addresses 158, 159: Un\G158, Un\G159). Note that initial setting processing will be executed if there is a sequence program that will perform initial setting when the module ready (X0) turns on. Also, for only the Q64TD, the error is cleared when the mode is switched. The factory default offset/gain values, user range settings offset/gain values and user range settings thermal EMF offset/gain values (buffer memory addresses 160 to 255: Un\G160 to 255) are related with the user range save/restore function and allow users to re-set the offset/gain values easily in the case of online module change. These areas are not used for the offset/gain setting

84 4 SETUP AND PROCEDURES BEFORE OPERATION (3) Program examples The program in the dotted area of (a) is common to (a), (b) and (c). In this example, the I/O signals for Q64TD/Q64TDV-GH are X/Y0 to X/YF. Offset request... M0 Gain request... M1 Write request... M2 Mode switching... M3 Offset/gain temperature set value... D0 Dedicated instruction (G.OFFGAN) set value storage device... D1 (a) When dedicated instruction (G.OFFGAN) is used to change mode The following program example is designed to shift to the offset/gain setting mode using the dedicated instruction (G.OFFGAN) and write the offset and gain values of CH1 to the Q64TD/Q64TDV-GH

85 4 SETUP AND PROCEDURES BEFORE OPERATION (b) When switching the mode using the setting of the mode switching setting (buffer memory addresses 158, 159: Un\G158, Un\G159) and operating condition setting request (Y9) Switch to the offset/gain setting mode. Sets 4144H to buffer memory address 158. Sets 964H to buffer memory address 159. Turns ON operating condition setting request (Y9). Turns OFF operating condition setting request (Y9) Common program Switches to normal mode Sets 964H to buffer memory address 158. Sets 4144H to buffer memory address 159. Turns ON operating condition setting request (Y9). Turns OFF operating condition setting request (Y9). Processing normal mode (c) When switching the mode by making intelligent function module switch setting Only the common program is necessary

86 4 SETUP AND PROCEDURES BEFORE OPERATION 4.7 Cold Junction Temperature Compensation Yes/No Setting The Q64TD/Q64TDV-GH can perform the following two different cold junction temperature compensations by making intelligent function module switch setting (switch 4) to select whether a cold junction temperature compensation will be made or not using the Pt100 temperature-measuring resistor. (1) Pt100 temperature-measuring resistor is used to perform cold junction temperature compensation (cold junction temperature compensation set for "Yes") A cold junction temperature compensation using the Pt100 temperaturemeasuring resistor attached to the Q64TD/Q64TDV-GH is made automatically. Q64TD Object whose temperature is to be measured RUN ERROR Pt Compensation conductor (copper) Thermocouple (2) Cold junction temperature compensation is performed externally (cold junction temperature compensation set for "No") Use this compensation when you want to make temperature measurement at so high accuracy that the cold junction temperature compensation accuracy using the Pt100 temperature-measuring resistor attached to the Q64TD/Q64TDV-GH cannot be ignored as an error. By providing a precision ice bath externally, the thermoelectromotive force generated at the tip of the thermocouple can be led to this module without any change, improving the cold junction temperature compensation accuracy. Q64TD Object whose temperature is to be measured RUN Pt100 ERROR Copper Compensation conductor (copper) Thermocouple Ice bath POINT The ice bath is designed to connect the thermocouple and conductor in the pot whose internal temperature is controlled to be 0 C. Hence, the thermoelectromotive force at the contact portion of the thermocouple and conductor will be 0mV, preventing the generation of extra thermoelectromotive force which can cause errors. Use the accessory Pt100 temperature-measuring resistor as it is connected

120 7 ONLINE MODULE CHANGE 7 ONLINE MODULE CHANGE When changing a module online, read the following manual. QCPU User's Manual (Hardware Design, Maintenance and Inspection) This chapter describes the specifications of an online module change. (1) Perform an online module change by operating GX Developer. (2) To ensure ease of offset/gain re-setting, there is a user range save/restoration function that is performed by executing the dedicated instruction or read/write from/to buffer memory. 7 POINT (1) Perform an online module change after making sure that the system outside the programmable controller will not malfunction. (2) To prevent an electric shock and malfunction of operating modules, provide means such as switches for powering off each of the external power supply and external devices connected to the module to be replaced online. (3) After the module has failed, data may not be saved properly. Referring to Section , therefore, prerecord the data to be saved (Factory default offset/gain value/user range settings offset/gain value/user range settings thermal EMF offset/gain value in the buffer memory). (4) It is recommended to perform an online module change in the actual system in advance to ensure that it would not affect the other modules by checking the following: Means of cutting off the connection to external devices and its configuration are correct. Switching ON/OFF does not bring any undesirable effect. (5) Do not install/remove the module to/from the base unit, or the terminal block to/from the module more than 50 times after the first use of the product. (IEC compliant) Failure to do so may cause malfunction. (Note) The dedicated instruction cannot be executed during an online module change. When using the dedicated instruction to execute save/restoration, therefore, execute save/restoration in the other system 1. If the other system is unavailable, execute restoration by performing write to the buffer memory. 1 If the module is mounted on the remote I/O station, execute save/restoration in the other system mounted on the main base unit. (Save/restoration cannot be executed in the other system mounted on the remote I/O station.)

(d) (e) (f) (g) Choose [Online] - [Debug] - [Device test] on GX Developer and set the values prerecorded in Section (2) to the buffer memory. Turn the user range write request (YA) from OFF to ON to restore the user set values to the module. After confirming that the offset/gain setting mode status flag (XA) is ON, turn OFF the user range write request (YA). Enable the conversion of the channel to be used through conversion enable/disable setting (buffer memory address 0: Un\G0), and monitor CH measured temperature value/micro voltage conversion value (buffer memory addresses 11 to 14: Un\G11 to 14) to check that proper conversion has been made. Since the new module is in a default status, it must be initialized by a sequence program after control resumption. Before performing initialization, check whether the contents of the initialization program are correct or not. 1) Normal system configuration The sequence program should perform initialization on the leading edge of Module READY (X9) of the Q64TD/Q64TDV-GH. When control resumption is executed, Module READY (X0) turns ON and initialization is performed. (If the sequence program performs initialization only one scan after RUN, initialization is not performed.) 2) When used on remote I/O network Insert a user device that will execute initialization at any timing (initialization request signal) into the sequence program. After control resumption, turn ON the initialization request signal to perform initialization. (If the sequence program performs initialization only one scan after a data link start of the remote I/O network, initialization is not performed.)

156 8 TROUBLESHOOTING POINT For the Q64TD, the code of the first error found by the Q64TD is stored when two or more errors occur. The latter errors are not stored. In addition, the error is cleared by mode switching. For the Q64TDV-GH, the code of the latest error found by the Q64TDV-GH is stored when two or more errors occur. The errors marked 1 can be cleared by turning on the error clear request (YF). The error marked 2 is not written to the buffer memory address 19 (Un\G19). It is written to the completion status area (S) + 1 of the G(P).OGSTOR instruction. 8.2 Troubleshooting RUN LED is extinguished Check that power is supplied. Check Item Check that the capacity of the power supply module is sufficient. Check for a watchdog timer error. Check whether the modules are loaded normally on the base unit. Is a module change enabled during an online module change? Remedy Confirm that the supply voltage of the power supply module is within the rated range. Calculate the current consumption of the CPU, I/O, intelligent function and other modules loaded on the base unit, and make sure that the power supply capacity is enough. Reset the programmable controller CPU and verify that it is lit. If the RUN LED does not light even after doing this, the module may be malfunctioning. Please consult your local Mitsubishi representative. Check the module loading status. Refer to Chapter 7 and take corrective action RUN LED flickers 8 Check Item Check whether the module is in the offset/gain setting mode or not ERROR LED flickers Remedy After making offset/gain setting, return to the normal mode. Check Item Check whether the switch 5 of the intelligent function module switches is "other than 0" ERROR LED is lit Remedy Set the switch 5 of the intelligent function module switches for 0.

Check for loose terminal screws. Check the connected thermocouple, compensation conductor or micro voltage signal cable for wire break. Check whether the channel where no thermocouple or micro voltage signal cable is connected is set to conversion enable. Remedy Connect the thermocouple, compensation conductor or micro voltage signal cable securely. Retighten the terminal screws within the specified torque range. Make continuity check on the thermocouple, compensation conductor or micro voltage signal cable, and change the thermocouple, compensation conductor or micro voltage signal cable if its wire is broken. Check the channels which are set to conversion enable and the channels where thermocouples or micro voltage signal cables are connected, and set to conversion enable correctly Measured temperature value/micro voltage conversion value cannot be read Check Item Check whether the used channel has been set for conversion disable. Check whether the programmable controller CPU is set for STOP. Remedy Set it for conversion enable in sequence program. Set the programmable controller CPU for RUN Measured temperature value is abnormal Check Item Check whether the connected thermocouple or compensation conductor differs from the setting. Check whether the connected thermocouple or compensation conductor is connected reversely. Check for noise in the thermocouple input. Check the Pt100 temperature-measuring resistor for making cold junction temperature compensation for wire break or disconnection from the terminal block. Check whether the cold junction temperature compensation yes/no setting is correct. Check whether conversion is made with the other thermocouple set after setting of the offset/gain value Is the measured temperature value greatly affected by a temperature error due to wiring resistance of the thermocouple? Remedy Set the thermocouple type connected to the switch 1 in the intelligent function module switch setting. Connect the thermocouple or compensation conductor correctly. Check influence from the ground and adjacent devices, and take action to prevent noise. Confirm that the Pt100 temperature-measuring resistor is connected to the terminal block and there is continuity, and if not, connect or change the Pt100 temperature-measuring resistor. Set the switch 4 to the correct position in the intelligent function module switch setting. (Refer to Section 4.5) Make offset/gain setting again after changing the thermocouple. Check the wiring resistance value of the thermocouple and calculate the temperature error in the system. (Refer to Section (2) for the Q64TD and Section (2) for the Q64TDV-GH.) If the temperature error is large, the error may be affecting the measured temperature value. Compensate the measured temperature value using the offset/gain setting. (Refer to Section 4.6.)

158 8 TROUBLESHOOTING Micro voltage conversion value is abnormal Check Item Check whether the input type set is a thermocouple or not. Check the micro voltage signal cable for noise.
